M80-4122001P Equivalent & Substitute Parts

Part Overview

The M80-4122001P is a 20-position receptacle connector from Harwin Inc.'s Datamate J-Tek series, designed for surface mount applications with 0.079" (2.00mm) pitch. This connector features gold-plated mating contacts and tin-lead plated posts, operating across -55°C to 125°C with UL94 V-0 flammability rating. The product is currently obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure procurement availability.

Key Parameters

Substitute Part Grouping Explanation

The M80-4122042 qualifies as a direct substitute for the M80-4122001P based on matching electrical and mechanical parameters. Substitution is valid where the following criteria are met:

• Identical connector type (Receptacle) and contact type (Female Socket)
• Matching position count (20 positions) and pitch specifications (0.079" mating pitch, 0.079" row spacing)
• Identical mounting configuration (Surface Mount, Solder termination)
• Matching contact material (Beryllium Copper) and mating contact finish (Gold)
• Identical operating temperature range (-55°C ~ 125°C)
• Equivalent insulation material (Polyphenylene Sulfide, Glass Filled) and flammability rating (UL94 V-0)
• Matching voltage rating (120V)

The primary distinction is product status: M80-4122001P is obsolete, while M80-4122042 is active and available.

Parameter Comparison

Engineering Selection Recommendations

The M80-4122042 is the appropriate substitute for the obsolete M80-4122001P. Both components are manufactured by Harwin Inc. within the same Datamate J-Tek series and share identical electrical and mechanical specifications across all critical parameters.

The M80-4122042 offers the advantage of active product status with current manufacturing support and availability. The contact finish on the post differs (Tin versus Tin-Lead), reflecting modern RoHS3 compliance of the substitute part. This change does not affect functional compatibility, as both finishes meet the same electrical and mechanical requirements for solder termination.

Mated stacking height variation (7.95mm versus 7.98mm) is negligible and does not impact PCB layout or mechanical assembly considerations.

Frequently Asked Questions (FAQ)

Q: Can M80-4122042 directly replace M80-4122001P in existing designs?

A: Yes. Both connectors share identical pitch, position count, mounting type, and electrical ratings. PCB footprints and mating interface specifications are equivalent.

Q: What is the significance of the contact finish difference (Tin-Lead versus Tin)?

A: The M80-4122042 uses Tin plating to comply with RoHS3 regulations, replacing the Tin-Lead finish of the obsolete M80-4122001P. Both finishes provide equivalent solder joint reliability and electrical performance for this connector application.

Q: Are there packaging differences between these parts?

A: The M80-4122001P packaging is not specified in available data. The M80-4122042 is supplied in Tube packaging. Confirm packaging requirements with your procurement specification.

Q: Do both connectors meet the same environmental and compliance standards?

A: Yes. Both parts are UL94 V-0 rated, operate across -55°C to 125°C, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected with EAR99 ECCN classification.

Q: What is the mated stacking height difference, and does it matter?

A: M80-4122001P specifies 7.7mm and 7.98mm; M80-4122042 specifies 7.7mm and 7.95mm. The 0.03mm variation is within typical manufacturing tolerance and does not affect mechanical assembly or electrical performance.
